Abstract: The invention relates to a test stand (100) for a powertrain of a motor vehicle (20). The test stand includes at least one loading motor (110) with a motor housing (111) and a motor shaft (112), at least one torque sensor (120), and at least one static module (130), wherein the motor shaft (112) is designed to be drivingly connected to a hub (21) of the motor vehicle (20) and wherein the torque sensor (120) is designed to detect a torque produced by the loading motor (110). The test stand (100) according to the invention is distinguished in that the at least one torque sensor (120) is arranged on the motor housing (111) in such manner that it blocks a rotation movement of the motor housing (111) relative to a substrate (119) and supports the torque via the motor housing (111) on the substrate (119).

Abstract: An electrode joining apparatus for joining a free electrode to a fixed electrode, the fixed electrode having a top end. The apparatus can include an electrode holder configured to selectively hold the fixed electrode. A torque device can be positioned above the electrode holder, the torque device configured to grip and spin the free electrode to join the free electrode to the fixed electrode. A blowout jet can be oriented to selectively force a stream of gas toward the top end of the fixed electrode when the fixed electrode is held by the electrode holder. As such, the blowout jet can help remove dust, debris, or graphite residue on the top end of the fixed electrode before joining of the free electrode to the fixed electrode. The fixed electrode can include a threaded socket, the blow jet oriented to force the stream of gas toward the threaded socket.

Abstract: An electrode joining apparatus for joining a fixed electrode and a free electrode including an electrode holder configured to receive the fixed electrode and a torque device positioned above the electrode holder. The torque device is configured to grip and spin the free electrode to join the free electrode to the fixed electrode. A force sensor is coupled to the torque device. The torque device is configured to apply a force on the force sensor when the torque device engages the free electrode. The force sensor can detect a feedback force signal representative of the force applied by the torque device on the free electrode. The feedback force signal can be used to determine the torque applied to the free electrode by the torque device to help ensure that a proper joint is formed between the free electrode and the fixed electrode.

Abstract: A high torque active mechanism for an orthotic and/or prosthetic joint using a primary brake which can be provide by magnetorheological (MR) rotational damper incorporating and an additional friction brake mechanism driven by the braking force generated by the MR damper. This combination of MR damper and friction brake mechanism allows an increase in torque density while keeping the same level of motion control offered by the MR damper alone. The increased torque density achieved by this high torque active mechanism allows to minimize the size of the actuating system, i.e. its diameter and/or breath, while maximizing its braking torque capability. In this regard, the friction brake mechanism is advantageously positioned around the MR damper, such that the dimension of the package is minimized.

Abstract: A printed circuit board may have embedded strain gauges. A strain gauge may be formed from a metal trace on a polymer substrate. The metal trace may form a variable strain gauge resistor that is incorporated into a bridge circuit for a strain gauge. The printed circuit may have a rigid printed circuit layer with a recess that receives the polymer substrate. Metal pads on the polymer substrate may be coupled to respective ends of the variable strain gauge resistor. The rigid printed circuit substrate with the recess may be laminated between additional rigid printed circuit layers. Vias may be formed through the additional rigid printed circuit layers to contact the metal pads. Embedded strain gauges may be used in gathering strain data when strain is imparted to a printed circuit during use of the printed circuit in an electronic device or during testing.
